Patent number: 11397005Abstract: A flow measurement device includes a flow rate measurement unit, an arithmetic unit that calculates a difference value between a the first flow rate value and a second flow rate value, and a difference value conversion unit that calculates a flow rate ratio, based on the difference value. An appliance characteristic extraction unit extracts at least one appliance characteristic quantity indicating a characteristic of a flow rate change and a value calculated from a first flow rate value and a second flow rate value, as an appliance characteristic quantity. Furthermore, an appliance inherent characteristic information holding unit holds appliance inherent characteristic quantities indicating a characteristic flow rate state of a specific gas appliance, and an appliance discrimination unit discriminates a gas appliance, based on a comparison between the appliance characteristic quantity and the appliance inherent characteristic quantity.Type: GrantFiled: November 15, 2016Date of Patent: July 26, 2022Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Yusuke Kitano, Mitsuo Yokohata
